Traterme

What Traterme does

Traterme - Tratamentos Térmicos, Lda. is a Portuguese privately held industrial heat treatment and engineering services company founded in 1991 and headquartered in Maia, Portugal. The company provides thermal and thermochemical treatments (hardening, nitriding, carburising, carbonitriding, annealing, tempering, stress relieving, hydrogen bakeout, shrink-fitting) for parts ranging from grams to tens of tons, delivered both at its nine-furnace Maia manufacturing facility and through mobile on-site teams that travel globally to client sites. It also operates specialized glass furnace lifecycle management (draining, controlled heating/cooling, cullet filling, regenerator cleaning) using proprietary high-velocity burners and water recycling systems, alongside refractory dry-outs, certified composite-material leak sealing (ISO 24817, ASME PCC-2), multi-process welding, and DGERT-certified training services.

The company's core technology stack spans electrical resistance, induction, and gas heating technologies across fixed furnaces and mobile modular furnace setups, with proprietary innovations in glass furnace management (high-velocity burners, scraper conveyor water recycling, vibration-based cullet filling). Traterme is the only company in the Iberian Peninsula certified to ISO 29001 for heat treatment in oil, petrochemical and natural gas sectors, and holds exclusive distribution rights in Iberian/Moroccan markets for Weldotherm GmbH, GH INDUCTION, 3X Engineering, and HOTFOIL-EHS. Its customer base includes major OEMs and EPC contractors across automotive (BMW, Mercedes-Benz, Volvo, Volkswagen), energy (Siemens, GE, EDF, EDP), oil & gas (Galp Energia, Repsol), construction (Fluor, Copisa), and glass (Lizmontagens).

Revenue is generated primarily through bespoke professional services contracts quoted on a project-by-project basis via email, complemented by hardware sales and rental of partner-brand equipment and consumables, and recurring DGERT-certified training revenue. Go-to-market relies on enterprise field sales, event-driven lead generation at industry congresses, and direct project execution through wholly owned subsidiaries in Morocco (2019) and the UK (2022), with local operations hubs spanning Senegal, Angola, Congo Brazzaville, Mozambique, France and Spain. The company has been recognized as PME Líder since 2011 and PME Excelência since 2014, and operates with no disclosed institutional investors, parent company, or public listing.
